Abstract: A system may have structure. The structures may include laminated structures formed by attaching inner and outer layers together with a layer of adhesive. The inner and outer layers in a structure may be formed from polymer such as polycarbonate. Forming the structure layers from polymer may allow the structure to have desired curvature. To improve safety and/or acoustic performance of the structure, the inner and outer structure layers may be formed from different materials. The outer polymer layer may be formed from polycarbonate and the inner polymer layer may be formed from a more brittle polymer such as polymethyl methacrylate (PMMA).

Abstract: Light-based devices may be provided that emit light. The light-based devices may be incorporated into systems such as vehicles. The light-based devices may include light sources such as light-emitting diodes and lasers. Mirrors may be used to collimate light from the light sources. Light modulators may be used to pattern light from the light sources. The light sources may include light sources of different colors. Arrays of pixels may be used to provide dynamically varying patterns of emitted light. A light source may produce light that is diffracted by an array of diffractive elements on a window. Mechanical and electrical shutters may obscure light sources, mirrors, and light-emitting components mounted on windows.

Abstract: A glass forming system includes a support that is configured to be installed in a glass bending furnace. The glass forming system further includes rods that are located adjacent to one another and spaced from each other to define a perimeter that encloses an open space. Each of the rods is coupled to the support. The glass forming system further includes actuators that are attached to the support. Each of the actuators is configured to move a corresponding one of the rods independently from the other rods. The glass forming system further includes a pad that is carried by the rods and that defines an engagement surface upon which a glass substrate is placed. A geometry of the engagement surface is reconfigurable based on movement of one or more of the rods.

Material may be included between the window layers and the different feature layers to fill any gaps. For example, trim and/or a masking layer may be used to match the appearance between the different regions.

The outer portion and the inner portion include different visual attributes.

Abstract: A window in a system may have inner and outer window layers. The inner and outer window layers may be formed from molded glass plates. The inner window layer may have a molded convex surface formed by molding a first glass plate against a mold with a concave surface. The inner window layer may have an opposing non-molded surface that does not contact the mold during molding operations and is smoother than the molded convex surface. The outer window layer may have a molded concave surface formed by molding a second glass plate against a mold with a convex surface. The outer window layer may have an opposing non-molded surface that is not contacted by the mold during molding operations and is smoother than molded convex surface. A layer of polymer may join the inner and outer window layers with their molded surfaces facing each other.

Abstract: A system may have windows. Each window may have inner and outer glass layers laminated together with polymer. Optical component layers may be incorporated into the polymer or the polymer may be free of embedded components. To avoid mismatch between adjacent window edges in systems with multiple adjacent windows, adjacent windows may be formed from shared-cut-edge-matched window panel sections that are cut from a common window panel. Windows may be formed from a single portion of laminated glass or may be formed by joining multiple smaller pieces of laminated glass together along a seam.

Abstract: A light guide may be embedded in a window. The light guide may have cladding and a light guide core layer embedded in the cladding. The light guide core layer may include a polymer layer configured to receive light from a light source. A selective area adjustable haze layer in the light guide core layer may have segmented transparent electrodes that can be controlled to cause one or more selected areas of the adjustable haze layer to become hazy. Light from the light source may be guided across the window within the light guide core layer in accordance with the principal of total internal reflection. When a dynamically adjusted hazy portion of the selective area adjustable haze layer is reached by the guided light, the guided light will be scattered out of the light guide.

Abstract: A system may have windows. Each window may have light guide structures. The light guide structures may be formed between inner and outer glass layers. Light sources may emit light into the light guide structures. The light guide structures may include light guide core layers that guide light from the light sources across the window. Light-scattering structures may be provided to extract light from the light guide core layers. Some of the guided light may be extracted inwardly to serve as interior illumination for the system. Some of the guided light may be extracted outwardly. The outwardly extracted light visually obscures the interior region from the outside of the system, thereby providing system occupants with privacy.

Abstract: A system may have system controls that are used in controlling the system. The system may have sensors that gather information on speed, orientation, and position. The sensors may also gather information on relative speed, information on risks of a collision, and other status information and operating environment information. Control circuitry may use light-based devices to display, information on speed, relative speed, status information, custom light information or other user-selected information, or other information on status and the operating environment.
